Why are airplane windows oval? In the early 1950s, the world’s first commercial jet was developed and manufactured by De Havilland. This is considered the miracle of the aviation industry. However, after a year of use, the plane fell to pieces right in the sky and within a few months, two more suffered the same fate. Engineers scrutinized the plane’s screws and discovered that the main cause was the square window. With this design, the pressure is higher at the door corners and increases significantly in flight. So the engineers decided to replace it with round or oval windows. Why do airplanes have curved wing tips? During a flight, the pressure on top of the wing is lower than the pressure under the wing. Air tends to shift from high pressure below the wing to low pressure above and around the wing tips. In the past, the wing tips were designed to be straight, causing the airflow to cause serious turbulence. Therefore, the scientists decided to bend the wing tip upwards to reduce turbulence, prolong the durability of the wing and save a lot of fuel during travel. Thanks to this feature, everyone will feel more comfortable during the flight. Why do airplane noses have different shapes? The nose of a military aircraft is pointed, the sharper the nose, the faster it flies. However, if the nose is too long, the pilot cannot see the runway correctly, which is why civil aircraft have round noses. Russian engineers solved this problem in the 1960s. The fastest passenger jet could tilt its nose. During takeoff and landing, the aircraft tilts its nose down and during flight the nose will be brought back to its original position. This strange design is intended to help pilots see the runway better. Why are airplanes painted white? Airplanes are almost always painted white. There are several reasons to explain this problem: Heat Reflection: A plane painted white will accumulate less heat. This is better for passengers and economically beneficial for airlines.
White paint is cheaper than other paints.
Prevent bird collisions: Birds can see reflections from white surfaces better, reducing the risk of collisions with aircraft.
White paint helps reveal small cracks and dents: The paint makes cracks easier to see, identifies problems early, avoids accidents, and makes damage easier to see. Why is the exit on the left? Not all but most aircraft have the main entrance on the left side. There is an explanation: The right side is for luggage (the cargo hatch is also on the right) so it is not safe for passengers.
Some say it’s an old tradition: The train ramp is always on the left.
The aircraft door is installed on the left side, which allows them to park the plane in the passenger area better and move more easily. Why are some planes oddly shaped? You must have heard of stealth aircraft. It has an odd shape to avoid detection by radar, sonar, infrared and other detection means, and to be able to carry more luggage with less fuel consumption. The shape of the plane is inspired by birds. Birds of prey use that shape to increase their range and be less visible. However, these aircraft are often too expensive to be used in civil aviation. How do airplanes look spacious? The designers use a number of tricks to make the plane look taller and more spacious than it actually is. For example, the walls have certain shapes to reflect light correctly. The illumination between the ceiling and the overhead bin makes the ceiling visually taller. Thanks to these tips, people with plane phobia will feel more comfortable. Why don’t pilots have beards? Some airlines ban pilots from growing beards. This is explained that, the beard can cause the oxygen mask to not fit tightly to the pilot’s face and work properly in an emergency situation. In particular, in that case, the pilots must always be alert to save the lives of passengers on the plane.

Collagen is a protein that the body makes naturally. It makes up about 33% of the total protein in the body and 70% of the skin structure. It keeps the skin elastic and smooth and reduces wrinkles and pigmentation. However, from the age of 25 onwards, the body begins to age. Collagen will gradually be deficient. The amount of collagen produced will not be able to make up for the lost amount, so the condition of the skin degrades very quickly. Collagen – a precious gift for health (Artwork) Recognizing this importance, the method of beautifying the skin with collagen was born to meet the needs of women. There are many ways to supplement collagen for the body such as: applying collagen-based products, injecting collagen, infusing collagen or taking collagen… Among them, drinking collagen is more popular both in terms of convenience, ease of storage and having Fast acting, easily absorbed into the body of the user.

“Every day, it must take a few hours to put on makeup and clothes, right?” “I’m curious, do they dress differently than normal people?” Above are the statements that fashion students often hear. The fashion design industry has been present in Vietnam for a long time, but for many people, this is still something strange, even… mysterious and probably also a convergence of real styles. divergent. From there, everyone came to a conclusion that: students in this major are very strange, very strange, very outstanding and must be very “art art”! Not necessarily! Students majoring in Fashion Design – Faculty of Art Design below have shown us a different view of the way the girls and boys dress up for school. Casual style is simpler than imagined Throughout the interview, black and white were the most popular color duo of the students. Easy to find, easy to wear, easy to mix, why not only the students in general but the students of Fashion Design here also have to “fall in love” before this combo. However, each of you still has your own highlights to affirm your own style which is quite interesting. Thuan – the 21-year-old girl chooses a youthful outfit with a white t-shirt with a pattern printed on it and a rather personal statement, combined with a thigh-slit black skirt. She did not forget to use accessories such as metallic necklaces and colorful bracelets as accents Vo Le Nguyen Phuong’s friend wears an outfit in the right summer spirit with a white crop top shirt over high-waisted pants and sneakers. It can be seen that the weather is hot, so you also prioritize items that are more comfortable and airy, not too picky Anh Dao (left) and Thien Thanh (right) bring two completely opposite styles. While Anh Dao has a personality with a white shirt with asymmetrical design, cut-out at the shoulder, mixed with a layered mini skirt and chunky boot, Thien Thanh, although also chooses a cut-out design at the shoulder, brings it to him. discreet and gentle image in my full black outfit Although wearing a Japanese schoolgirl outfit and wearing hime hair, her friend Tran Ngoc Phuong Lan confided that she is not really a crazy fan of Phu Tang fashion, but simply wants F5 to be stylish. Instead of choosing a safe white sneaker, she chose a pair of funny patterned sneakers with lovely pink socks, creating a great highlight for the overall. No need to look closely at the outfit, but Tran Minh Bao Long is also impressive enough with orange-yellow hair and a personality tattoo on his hand. Wearing all black, but he did not bring a dull feeling thanks to a pair of metallic bomber jackets and pointed leather boots. Besides, his thin, tall figure also makes him look very “artist”. This is probably the most “colorful” person in the interview. In contrast to the gentle, slightly shy reply in the video, Chi Cuong shows that he has a very good taste in clothes and coordination. The guy mixes a shirt with a tropical vibe with a ruffled leopard-skin sweater in the style of an inside shirt, slightly flared leather pants, a platform boot and a black beanie hat to balance the other two outstanding items. Full of enthusiasm and passion when sharing about your favorite designer Internationally renowned designers such as Jacquemus, Rick Owen, Jil Sander, Yves Saint Laurent and Maria Grazia Chiuri are fashion figures loved by students.

Pitbull is considered a fierce, aggressive, persistent, tenacious dog that is even compared to a cold-blooded killer by dog ​​lovers. In the US, the Pitbull is considered the most dangerous breed and is used in professional dog fights. In Vietnam, many people show their class from raising Pitbull dogs worth a few dozen to several hundred million dong. Fierce dog breed, originating from England According to dog site BarkPost, pitbulls are often mistaken for American dogs – in fact they are of British origin. In the early 18th century, the ancestors of the modern pitbull followed the British to emigrate to America. At that time they were trained to keep the farm, hunt and keep company with the owner. To suit the working conditions and living environment in the US, especially the fierce hunting – Pitbull was deliberately bred to be bigger and more aggressive to hunt large animals. In the early 18th century, the ancestors of the modern pitbull followed the British to emigrate to America. At that time they were trained to keep the farm, hunt and keep company with the owner. To suit the working conditions and living environment in the US, especially the fierce hunting – Pitbull was deliberately bred to be bigger and more aggressive to hunt large animals. Due to the characteristics of the skeleton as well as the muscles, the pitbull is famous for its tenacity, endurance and especially aggressiveness if provoked. The average Pitbull has an average weight of 30-40kg, those with special care can reach 80kg, an adult height of 45cm or more with sharp teeth. – Out of a total of more than 400 dog species of the modern world, the pitbull is ranked in the 11 most dangerous dog breeds for humans. – According to LawFirm, 69% of dog bites leading to death or death are related to pitbull; 76% of people killed by dogs in the past 50 years are pitbulls, of which: 27% are children (more than 2/3 are infants or under 2 years old). Why can pitbull get mad, bite people to death? According to many connoisseurs of breeding and training Pitbull dogs are really massive, aggressive but loyal to death to protect their owners. Their madness to bite people to death mainly comes from 2 factors: First: The “a-dua” raising dogs according to the movement, lack of knowledge, even to fight dogs, many owners have intentionally injected stimulants, fed raw meat to pitbull muscle development. Besides, if you are kept in a tight space, neglecting in training will cause the pitbull to be stressed and have excess energy. If the above situation is prolonged, the pitbull will suffer from depression, nervous inhibition leading to uncontrolled violent actions even with mild agitation. This doesn’t just happen with pitbulls, it’s the same with most large dogs. Second: Today’s Pitbull is essentially the product of a “hybrid race”. Many dog ​​breeders are always looking for ways to create a pitbull that is superior in appearance and strange in color by crossing it with many other dog breeds. Besides the purpose of improving appearance, this causes psychological instability for pitbulls in the next generations. Similarly in the past, humans have sought to cross domestic dogs with wolves to create new species that are beautiful and unique. However, the evidence is that crossbreeds that lack selection often have wild, unfriendly behavior and they will attack people sooner or later. Thus, whether the pitbull is good or bad – most of it comes from the owner’s upbringing and training. Experience in dealing with pitbull dogs According to a dog trainer, attacks involving dogs usually fall into two phases. Before being attacked: Be especially alert, pay close attention if you see pitbulls (and large dogs) loose, not muzzle appearing at the place you pass. If the dog growls, stares and starts to move closer, stay calm – find something that makes you look taller like a coat, tarp, cane… and point it in front of you. Maintain a defensive stance and slowly step back to create some distance. Absolutely do not turn to run away, this will activate the hunting instinct in dogs, making them rush to attack you immediately. While under attack: In case the dog still rushes to attack, knock you down – the part they will target first is the face and neck of the victim. Do everything you can to cover the head and neck as well as kick the dog’s neck, shouting for help. Pitbull when biting people will lock the entire jaw. The act of pouring water, setting fire to the muzzle, hitting the dog’s butt and back is not recommended because the more you hit it, the more fearful it feels, making it more aggressive. According to longtime Pitbull owners, they often subdue this species with a “fangs” – a specialized tool used to open the jaws of aggressive dogs. In addition, it is also possible to affect the lower jaw of the dog or find ways to influence the inner jaw so that the dog opens the jaw. According to dog trainers, the part that needs to be attacked to stop the dog is the COLLEGE. Hits hard enough on the pitbull’s throat will make them falter. However, all preventive measures are not as effective as dog owners consciously muzzle when taking the dog out. About 39 countries or some provinces/states of the country ban the breeding of Pitbulls. Among these are Argentina, Bavaria, Belarus, Bermuda, Denmark, Ecuador, Finland, France, Guyana, Ireland, Israel, Italy, Latvia, Liechtenstein, Malaysia, Malta, New Zealand, Norway, Poland, Portugal , Puerto Rico, Romania, Russia, Singapore, Spain, Switzerland, Turkey, United Arab Emirates (UEA), Ukraine, United Kingdom, and Venezuela are banned nationwide. Meanwhile, 15/16 states in Germany ban Pitbull dogs. In addition, some areas in Australia, Austria, Belgium, Brazil, China, Canada, and Japan also ban this breed. Among these countries, Italy lifted its ban on dangerous breeds of dogs, including the Pitbull, in 2009.

Share information about which type of collagen is good, experts say. Currently, collagen is divided into many different forms. In particular, each type of collagen has its own advantages and disadvantages. Accordingly, depending on the purpose, or the need to use collagen, you will choose the best type of collagen. Illustration On the market today collagen is also divided into forms such as collagen powder, collagen tablets, collagen oral form. Specifically, the advantages and disadvantages of each type are as follows: Collagen powder Powdered collagen is a new type of collagen that has recently appeared in the Vietnamese market. Trusted by many women. With powdered collagen, the biggest advantage is not only in efficiency. And this type of collagen also ensures high safety for users. Moreover, users can use powdered collagen to mix with fruit juices. To enhance the efficiency of use without affecting the quality and taste of the product. However, compared to liquid collagen and tablets, powdered collagen has the disadvantage that it is more difficult to buy in the market. Water-based collagen Water-based collagen is sought after by many women today. Liquid collagen has advantages such as higher absorption than tablets and powders. Liquid collagen is widely sold in the market, also easier to find because of its mass. However, this type of collagen also has some disadvantages such as: High cost, difficult to drink and difficult to store. Collagen tablets Collagen tablets appear quite a lot on the Vietnamese market. Rated as the easier to drink of the 3 types of collagen and can be carried anywhere, the price is relatively cheaper. Although chosen by many women, this type of collagen still suffers from some disadvantages such as: Lower efficiency in collagen types. Because, when supplementing with collagen in the form of tablets, it takes time to dissolve, so the effect will be longer and slower. However, depending on the preferences and desires of each individual, you can actively choose your own type. Illustration It can be said with the above analysis. Surely readers can find the answer to the question: “Which type of collagen is good?” At the same time, it is possible to choose the type of collagen that is suitable for the body, for the best effect.

People do not use plastic bottles to pack beer for the following reasons: Plastic is a more porous material than glass, so it makes beer easier to “pale” when stored in plastic bottles instead of glass bottles because of the gas in the drink. will be more susceptible to evaporation. Glass has almost no effect on taste because of its chemical inertness. In contrast, plastic contains a lot of chemicals that can dissolve into beer and affect the taste, even the quality of the drink. Like glass, aluminum is a completely waterproof material, making it ideal for beer storage as well. But unlike plastic, the inside of aluminum cans is coated with a special polymer that prevents aluminum from leaking into the drink, so they are much safer. In addition, unlike the two materials above, aluminum completely blocks light, helping drinks in aluminum cans be better preserved than other types of bottles. Another problem with plastic bottles is that they cannot withstand the sterilization process that most beers go through. After being brewed and bottled, beer will usually have to be put through a machine that sprays boiling water to kill any bacteria that are still alive after the fermentation process. This process is both to ensure food safety and to increase the shelf life of beer. And while glass bottles or aluminum cans can easily endure the process, plastic cannot. That means either we have to skip the sterilization process, or we have to choose a more durable plastic, which means higher costs. For the above reasons, it can be seen that glass bottles and aluminum cans will still dominate the beer industry worldwide. Transparent beer bottles left in the sun often cause beer taste changes such as musty odors and odors, because UV rays from sunlight easily pass through the beer bottle shell to react with the sulfur molecules present in the beer. , creating a strange taste and difficult to drink like broken beer for a long time. Therefore, to overcome that situation, manufacturers have created beer bottles in brown and green colors, because these two colors prevent the best absorption of UV rays.

The prairie lynx is a wild cat that is distributed in Africa and possesses the longest legs, of any cat with similar body size. Grass lynx has the scientific name Leptailurus serval. This wild cat species distributed in Africa, was first described in 1776. Grass lynx has a heat cycle that lasts up to four days, and is usually at the time when kittens will be born just before the peak breeding period of local rodent populations. They can be born many litters a year, but usually only if the previous litter dies shortly after birth. The pregnancy cycle lasts 66-77 days and usually produces two kittens, although sometimes more. Kittens are born in dense vegetation or a cave left by a piggy bank. Otherwise they can give birth under a shrub. Grassland lynx has a slender body, medium size, weight from 9kg – 18kg. Grassland lynx can travel 3–4 km per night in search of food. The long legs (longest of all cats of the same body size) show their adaptations to the steppe lifestyle, helping them reach a top speed of 80 kilometers per hour, and large ears with hearing. Very good at allowing them to detect prey, even in the ground. They can jump 2–3 m high to catch birds in flight and can jump up to 3.6 m. They are effective predators with a success rate of up to 50%. Grass lynx has a small head, large ears, an outer coat colored from golden to dark yellow with black spots and stripes, and a short tail with black tops. In particular, the prairie lynx has the longest legs of any cat with similar body size. It is the long legs that help the grass lynx achieve a maximum speed of 80km / h while the large ears allow them to detect prey even in the ground. Grass lynx usually hunts rodents, they also feed on birds, hares, hyrax guinea pigs, reptiles, insects, fish and frogs. Kittens weigh about 250 g at birth, and have not opened their eyes at first, with gray fur. They open their eyes between 9 and 13 days old, and start eating solid foods after about a month. By about six months, they have fangs and begin to learn to hunt, and will leave their mother by about 12 months. They reach maturity between 12 and 25 months of age. Their average lifespan is about 10 years in the wild, and up to over 20 years in captivity. Grass lynx confronted with leopard Clashes between grass lynx and cheetahs caught on the lens of Gavin Newfield, visitors to the Pilanesberg nature reserve, South Africa, Latest Sightings on February 16 reported. While Newfield was engrossed in watching a wildebeest, his girlfriend spotted a lynx nearby and showed it to him. It seems to be in conflict with the cheetahs hunting about the territory. “Four cheetahs, a grassy wildcat and a wild gazelle are the best sight I’ve ever seen,” says Newfield. Before that, he and his girlfriend had never seen a grass lynx. In the video, the grass lynx, despite its smaller size, still tries to confront the leopard. It and the same leopard came out in the middle of the fighting street, while the rest of the leopard was located close by. “In the end, the grass lynx ran away from the territorial battle. Upon seeing the lynx’s action, the leopard also rushed in that direction. Both disappeared from sight. Meanwhile, the 3 predators remained. chasing the wildebeest again, causing the animal to run away, “Newfield said. Grass lynx (Leptailurus serval) is native to Africa. They are skilled hunters, often targeted at rodents, reptiles, birds, frogs, and insects. Grassland lynx rarely has to eat scavengers. They can jump high to catch prey or catch fish swimming in the water. Video of a prairie lynx confronting leopard:

That equates to 500 liters of water. This is the highest daily loss of water of any terrestrial animal. Elephants lose more water when the weather is hot Elephants are inherently endangered, dehydration from hot weather can lead to lower birth rates, loss of milk to young elephants and death from dehydration. Elephants drink hundreds of liters of water per day, but it is not clear how climate change will change their water needs as of now. So in the new study, researchers led by conservation biologist Corinne Kendall looked at five African savanna elephants (Loxodonta africana) at the North Carolina Zoo. Over the course of three years, the team fed the elephants six times with deuterium – a heavier version of hydrogen, harmless, water-soluble and traceable back in the liquid the elephant was released. The scientists routinely took blood samples for 10 days after feeding the elephants with deuterium to see the remaining amount each time, thereby calculating the rate of excretion in the elephant’s body. The results were “staggering,” Kendall said. At cool temperatures (between 6 ° C and 14 ° C), males lose an average of 325 liters of water per day. But at about 24 ° C they lose an average of 427 liters, and sometimes go up to 516 liters, the team wrote in the Royal Society Open Science. 400 to 500 liters of such water is equivalent to 10% of the total water in the elephant’s body – or up to 7.5% of the body mass. One elephant lost nearly 9% of its body mass in just one day, says Rebecca Rimbach, an ecological biophysiologist at Duke University. However, because elephants continuously replenish lost fluids through drinking, eating, and metabolism, the elephant’s actual daily water loss is lower. In general, elephants must drink water at least every two to three days to avoid “dangerously high levels of dehydration,” Rimbach said. Worryingly, as global temperatures get higher and higher, elephants will need to drink more water. But also due to rising temperatures, water scarcity, water holes dry up, and water-rich plants become more difficult to find. Study co-author Erin Ivory, behavioralist at the North Carolina Zoo, said this double effect could also exacerbate conflict between wild elephants and human populations, when elephants attack the season. membrane or destroy groundwater infrastructure, violent confrontations that can be fatal for both humans and elephants. And the elephants that not everyone knows On average, the ear sizes of an African elephant and an Asian elephant are very different. The African elephant’s ear is three times larger than the Asian elephant’s. African elephants tend to use their long ears for reasons such as signaling or protecting others. Females spend their entire lives with their families including mothers, grandmothers, aunts, sisters and daughters, an adult female elephant often leading the party. Adult male elephants prefer to live a single life. Both African and Asian elephants use their ears as a conditioner to regulate their body temperature. The elephant’s tusks are mainly from … incisors An elephant’s tusks grow from their front teeth throughout their lives. The tusks of an adult elephant can grow 7 inches (17cm) per year. Ivory was used to find salt, water and plant roots, remove bushes, clear paths and were sometimes used in combat. In addition, they are also used to mark trees to establish an elephant’s territory. Despite having large ears, the hearing of an elephant is very poor. They can live up to 70 years. Their spout has no bones. More than 150,000 muscles and nerves provide their hose flexibility. Additionally, an elephant fills its hose up to 5 liters of water and then pours it into its mouth to drink. The elephant listens with its feet and ears. This large mammal can drink up to 80 gallons of water in a day.

Dolphins evolved from a species of terrestrial animal Dolphins evolved from a species of terrestrial animal Dolphins are mammals, closely related to whales, often living in shallow seas on the continental shelf. Dolphins have the ability to understand simple human behavioral language. With their inherent magical abilities, dolphins can understand and organize common objects into a group together. They understand both sounds and images, and even reflect images that are no different from people. Explaining this, scientists have confirmed that dolphins are the most intelligent animals in the world (while humans are only third in intelligence). Millions of years ago, the ancestors of dolphins did not swim underwater as we know them today, but were a predator that lived entirely on land. However, about 50 million years ago, a mysterious event happened that forced them to adapt to the aquatic environment, and gradually evolved into a species of mammal today. Although considered an extremely friendly animal, dolphins also have creepy behaviors, typically juggling young animals out of the sea. It sounds like a very interesting joke, but in fact, it is one of the ways the adult male is killing the young so that their mother can return to mating. Dolphins may not sleep for many weeks A recently published study has shown a surprising ability of dolphins: Can stay awake for days or weeks continuously without sleep. So how can they survive without sleep? Dolphins have a very special sleep mechanism, they can give half of their brain a rest at a certain time when the other half is awake – a process called “Unihemispheric sleep”. This special sleep mechanism not only prevents dolphins from drowning, but also allows them to stay alert to any danger and even encourage brain development. Most dolphins do not chew their food Dolphins do not chew food, or rather they cannot. A dolphin’s teeth are developed for the purpose of gripping prey. Sometimes they will shake or rub food on the ocean floor to tear them into small pieces to make them easier to swallow. One theory is that dolphins’ prey is mainly small fish, and they need to quickly grab prey in their mouth before their meal can swim away. Skip the chewing process to make sure the prey doesn’t escape. Dolphins call each other by their own names, forming friendships through common interests Researchers from the Universities of Bristol, Zurich and Western Australia have found that dolphins living in the Shark Bay area form friendships based on shared interest – in this case, a habit of using foam. sea ​​for prey. This tool-use trait is found mainly in female dolphins, but by studying the behavior of a few male dolphins that exhibit expression, the researchers have found a new discovery: Dolphin’s are formed through general tooling techniques. Dolphins have a given name and they will respond when called. Dolphins in each population possess their own “signature whistling”, as a name and other dolphins can use that particular whistle to get their partner’s attention. In fact, dolphins are also an extremely social species. This finding opens up entirely new questions about dolphins’ communication levels and “vocabulary”, and may reveal clues about our own evolution of language skills. Dolphins use their prey toxins as “addictive substances”. We know that puffer fish are highly toxic. Obviously dolphins know this too, but they use it for “high”. Usually, the puffer fish toxin is lethal. However, in small doses, it can act as an addictive substance. The BBC has recorded a video in which dolphins gently play with a puffer fish for 20 to 30 minutes, then hang around without leaving and behave “strange”. Dolphins possess great “teamwork” ability A team of researchers from the University of Bristol recently discovered that male dolphins can work and work together as a team – an attribute previously thought to be unique to humans. Observing the behavior of male dolphins when they were coordinating flirting with female pigs, the researchers found cooperation rather than competitive behavior, which is especially unusual in finding a mate in the animal kingdom.

In C-Biz, Duong Mich still scores points for a variety of fashion styles but still remains trendy. From the casual clothes to the red carpet of Duong Mi has been highly appreciated by the audience. In the past, Duong Mich loved to wear shorts or short skirts, and then fashioned a shirt to hide her pants to show off her extremely long legs. But recently, she changed her style with wide-legged pants, a cardigan that showed off her slim waist and blazer. Looking at Duong Mich full of ways and differences makes the audience extremely excited. But soon, many people realized that Duong Mi’s set was almost identical to Jennie of the Korean group BLACKPINK. Both stars have touched the line of Cardigan black and white stripes of the famous fashion house Chanel. If it was just a simple encounter, then I would not say anything, over here Duong Mich was also considered by netizens to be too similar to Jennie. A member of the BLACKPINK group also combines a badger shirt with loose pants, white sneakers and a black blazer. If there is anything different, Jennie also adds a scarf to make a highlight. Jennie’s fans believe that the Korean female idol is becoming more and more popular, considered a trend-setting girl, so many people learn it is understandable. However, many fans of Duong Mich insisted that this was just a random encounter, but there was no imitation of style here.

Both Suzy and Jisoo are the faces representing Dior, so the encounter is inevitable and always makes the audience admit that Dior chose her too well, everyone is beautiful. Although the two girls have never appeared together at a Dior event, they have been different when wearing clothes. Sometimes Suzy looks more impressive, sometimes Jisoo looks sweeter, but in short, both are extremely beautiful. Four ad encounters with Jennie It is normal for brands to change advertising models, but when Jennie has 4 times to act as “Suzy’s successor”, it is not normal at all. Most recently, Jennie became the new muse of a nail care brand. Previously, Jennie replaced Suzy as a model for a traditional Korean beverage brand. The two girls even wore similar outfits on the promotional photos, making netizens even more comparable. Both Jennie and Suzy are the faces of the Vita500 nutritional drink, with a radiant youthful image. For much longer, Jennie is also a model for the lemon-flavored carbonated drink brand after Suzy, both female idols also take pictures. concept Wearing clothes that show off her full body shape, water bottles held up high, and charming wet hair. Was once suspected of … dating Rosé The reason is that in September 2019, the two girls had continuously had suspicious coincidences on Instagram. Both idol they all departed for Paris for fashion week on the same day, Suzy was Dior’s special guest and Rosé accepted Saint Laurent’s invitation. The two girls uploaded photos on the plane with the same shooting angles and very similar comments. It is possible to see Suzy and Rosé traveling with the same airline, it is only unknown whether the two girls will fly on the same flight or not. During their time in Paris, both Suzy and Rosé spent time visiting the home of famous painter Monet, which is a popular tourist destination in the French capital. Apparently the two girls took pictures at the same flower cluster, even used it Icon but not the text for this post. However, many people believe that this is just a coincidence.

All objects falling into the air have terminal velocities depending on their size, shape and mass. The terminal velocity of an ant (6.4 km / h, according to the physics department of the University of Illinois) will be much different from the human terminal velocity (about 200 km / h). “For rats and any small animal, there’s really nothing dangerous. You can drop a mouse into a mine nearly 1,000 meters deep and when it hits the bottom, it gets dizzy and runs away. , provided that the ground is quite soft The air resistance acting on the moving object is proportional to the surface of the object.If the length, width and height of an animal are divided by 10, then the mass. Its amount is reduced by 1000 times while the surface area is reduced by only 100 times, so the air resistance for small animals is usually 10 times higher than the actuation force. Force is usually not an issue for insects, it can fall freely without danger, with the ability to cling. ” Michael Kaspari is an ecologist at the University of Oklahoma (USA), who has studied the aerial activities of wingless ants. Research shows that when ants are confronted with a predator, they jump in the air from tall branches and use their legs to steer their flight to the tree. The longer hind legs will allow the ant to travel through the air, preventing it from falling into places they deem dangerous. With this ability, it is possible that the ant has managed to cling to something before it falls to the ground, and whether it can grip or not, the ant will not die if it lands. The most ancient creatures still exist today It is thought that the earth currently has 10 million billion ants, despite the fact that they are killed a lot every day. According to biota, it is estimated that ants make up about 15-20% of the total number of terrestrial animals. Ants are animals belonging to the membrane wing, the layer of insects. Scientist Corrie Moreau and his French colleagues published a study that found ants appeared 140 to 170 million years ago. That means they are the most ancient creatures that still exist today, despite the intense fluctuations of the earth. Since then, it has been found that ants have a very high ability to survive in all weather conditions. Such survival is bestowed on nature, since they show no signs of consistent change. Which means it is very likely that an ant 170 million years ago and an ant now are no different. It is thought that the earth exists about 20,000 different species, with 4,500 families. They are found all over the earth. Even the extremely cold places are the poles of the earth, or the hot center of the equator. Ants come in many varieties, but the colors are usually just red or black. Especially, there is a species with white color added. Ants live in herds, with a quite separate social organization. Each nest has an average of about 100,000 children in a herd with a single mother (God ants, can live up to 30 years). Here, there is something like the way bees organize the swarms of life. The great majority of baby ants in the herd are worker ants (who only live 1-2 years) – such as the hardest and most hardworking workers on earth. The job of worker ants is to take care of queens, incubate eggs, transfer eggs, raise young ants, build caves, forage, guard … Few people know that all worker ants are female, but their reproductive organs are not fully developed, so they can never become God prejudices, but are forever just “cu-li” legs from birth. to death. Ants are considered the most powerful because they can carry food 10 times heavier than them. But to transport that heavy food, they have to use collective strength in coordination. Together, they carry the food they can find easily, when thousands of them work together. Ants are everywhere, anyone can see them or be stung by them, but few people know that they also have positive effects. The Masai people of eastern Africa have a habit of using ants as tools for wound healing. When one of the tribe was injured, they would capture a few large ones from the “army ant” group so that they would bite on either side of the wound, then remove the body, leaving only the ants on the wound. From there, the wound did not bleed and healed quickly. And interesting things about ants Ants are animals with a fairly sanitary life. Specifically the handling of the dead. When one is dead, the other ants in the herd together carry the dead ants out of the nest, with the sole purpose of keeping clean, avoiding infection or disease spreading. Worker ants will take care of carrying under the command of an ant that is believed to be responsible for the funeral of the flock. It was also surprising that ants were insects with a very advanced organizational system. Along with God ants, worker ants, and the commanding ants of burial, there are also “teacher” ants. Born, to have the necessary skills, they go through a learning process under the guidance of “teachers”. The “teacher” ants in the nest will teach the younger ants to do the necessary work. In the event that “students” learn slowly and “fail” on a test, they will be transferred to another job that requires less skills. Not only know how to find termites, but also know “breeding” to create a food reserve. They know how to feed insects such as aphids and moths to get the sweetness they produce. When it is time to harvest the sweeteners from the insect swarm, the ants “milk” using their antennae. It is extremely interesting to know that ant colonies carry a swarm of insects that they cultivate when moving to a new area. It is no different than humans taking cattle along to places where the grass is lush. People have talked about extraordinary in the ant world. They do not have ears but senses sounds from ground vibrations through the sensitive sensors on their legs. They have the ability to survive miraculously despite the extreme weather and climate. That is why ants are also one of the first organisms on earth to be sent to space by humans in experiments to conquer the sky. Ants have poor eyesight, in return they often use the earth’s magnetic field to guide their way. They are considered the smartest insects when there are more than 250,000 brain cells in the small head of ants. As a hard-working animal, ants are also said to be “great athletes”. If an ant was about the size of a human, then it could run at an average running speed of 55 km / h without ever getting tired. They can once again lift an object 50 times its weight with incredible strength.

Professor Chris Buddle of the Department of Insect Ecology at McGill University, Canada pointed out that: “Out of nearly 40,000 species of spiders in the world, only about 10 can be dangerous to humans. Even venomous species are very unlikely to come into contact with humans, let alone attack us. ” Are spiders any color? It sounds strange, but spiders don’t really have blood. What they have is called “Hemolymph”. In fact, our blood is based on iron-containing hemoglobin molecules, so they are red. However, the blood of the spider is based on the protein called Hemocyanin derived from copper. This hemocyanin has a fairly clear color, but when exposed to oxygen it turns dark blue. Spiders cannot digest food in solid form They have to pump a liquid into their prey to soften their internal organs and tissues. After everything is softened completely, spiders can suck the contents inside to nourish their bodies. Spiders can control their blood pressure while on the move Spiders not only use muscles to move, but they also know how to combine blood pressure to walk or jump, depending on the species. Spiders contract muscles in the nipples and increase hemolymph pressure in the legs, which makes it easier for them to expand the area of ​​movement. This sudden increase in pressure also caused their legs to leap in different directions. Spiders have no vertebrae Spiders have no bones. They have only a set of sclera surrounding the organs and blood. This makes them classified as invertebrates or non-vertebrates. However, spiders are not the only species with sclera. Practically all insects and arachnids have that set of sclera. Having a set of sclera allows these organisms to grow more and periodically they need to “strip off” or replace their sheath. They can also re-develop the body in a short time. All invertebrates (even spiders) are very vulnerable before their sclera can harden. There is a species of spider that actually lives in the water There is a species of spider that is adapted to live in water, also known as the “Diving Bell” spider. Special soft hairs surround their bodies in the shape of air bubbles that provide oxygen in this particular habitat. Spiders are also a vegetarian Bagheera Kiplingi Spider (Kipling Spider) was discovered in the 1800s, their main food is acacia buds and plants. Sometimes this spider also eats larvae. It is also the only vegetarian spider in the world. Spiders will eat back their old spider silk When the silk loses its cohesion or becomes too dirty, the spiders often eat it and use nutrients from the old silk to create a new web. Do you see ? The spiders recycle them… in their own way. Antarctica has no spiders. Antarctica is inhabited by spiders. These are simply places where the climate is so extremely cold that they cannot do the usual metabolic processes. N What will poisonous bites look like? However, you should still be aware of some spiders with venom that carry extremely dangerous venom. The red back spider in Australia has a venom that causes nerve damage to humans for 24 hours. The black widow spider is famous for its poisonous bite, affecting the relatively strong nervous system, but it is difficult to cause death. When biting the spider spider, the wound becomes infected, leading to blood infection and gangrene. Tarantula large black spider in the rainforest will make people fall into a coma immediately. 6-eyed sand spider will cause local clotting and wound necrosis.

Bear eat ants for a body length of 150cm but has a tongue up to 60cm long. True to its name, the bear eats ants, this bear eats ants, termites and a long, sticky tongue with small spines is a very effective “tool” in catching prey. With the speed of releasing and retracting the tongue up to 150 times / minute, ant-eating bears can catch up to 30,000 termites per day.

Ants’ stomachs have a special structure that can crush large numbers of ants and termites, helping to facilitate digestion. This stomach produces formic acid instead of the hydrochloric acid commonly found in other mammals.

Bear eat ants have poor eyesight, but the ability to smell very sharp, 40 times more than humans. They use their noses to find food. The body temperature of the ant-eating bear was 32.7 ° C, which is lower than that of other placenta, mammals. If living in the wild, ant-eating bears can last 15 years and 25 years if kept in captivity.

The bear eats pregnant ants for 190 days and gives birth to only one baby per litter. A bear that eats ants will stay with her mother for two years until the bear that eats the ant is pregnant again. In the first year of life, the bear eats the mother ants and will carry the baby on her back.

Bats suck honey

The honey-sucking bat is one of the famous bats for its long tongue. Its long tongue when retracted was hidden in the chest.

A species of bat with a tube-shaped mouth specializing in nectar absorption, or known as Anoura fistulata has the longest tongue of any mammal on the planet. The tongue of this exotic animal is about 8.5 cm long, 1.5 times its body length. According to Iflscience, this particular species of bat broke the record for the first bat species in Ecuado decades ago.

Now, according to the Association for the Conservation of Wildlife, a strange species of bat has been found for the first time in Bolivia’s Madidi National Park. This unusual tongue allows them to easily suck nectar from the ends of a funnel-shaped flower. This is also an effective way to pollinate this elongated flower.

In fact, with a tongue almost twice the length of its body, there is no animal in the natural world that has “overtaken” the long ratio of the tongue to the body of this bats.

Pangolin

Pangolins have a tongue up to 40cm long with a lot of sticky drool to easily catch prey. Its tongue stalks deep in the abdomen. This animal has no feathers, only a hard scaly covering its body, and also has no teeth. The pangolin’s food is mainly ants and termites.

British naturalist David Attenborough chose the Sunda pangolin (a species of pangolin distributed throughout Southeast Asia) as one of the 10 species he wants to rescue from the most endangered.

So what makes pangolins so special? Here are facts to help us understand more about one of the most endangered species on Earth.

Currently in the world there are about 8 species of pangolin in existence, and some species have been extinct during evolution over the past 80 million years. Four of them live in Asia: China, Malaysia, India and Palawan Island (Philippines), while the remaining 4 species are distributed in Africa.

When fully stretched, the pangolin’s tongue can be up to 40cm long and the base of the tongue is deep in the chest cavity. The pangolins use their sticky tongues to catch insects. Because pangolins have no teeth, they crush and digest food with stones in the stomach.

The scales of pangolins are mainly composed of keratin, similar to human nails, rhino horn or bird nails … The horn scales account for 20% of the weight of this animal. The very hard scales can protect pangolins from predators. However, in traditional Chinese medicine, people dry and roast pangolin scales because they believe they can cure polio, stimulate lactation for women … For that reason, the price of pangolin scales on the black market amounted to more than 3,000 USD / kg.

Red tree bark flattened beetle

This beetle about half an inch long has a habitat from North Carolina to the Arctic Circle. They live under the bark of a tree and their bodies are purposefully designed to survive the harshest conditions in mid-winter.

The arctic climate in August acts like the resting climate for this species. In laboratories, they can withstand freezing temperatures up to -150 degrees Celsius.

In fact, this is the coldest we’ve ever seen. They can overcome this extreme cold by forcing 30-40% less water in the body and preserving the remaining water by using antifreeze proteins between the cell membranes.

Thyme beef

Muskrats have lived in the Arctic for a long time, from the ice age about 200,000 years ago. With double-layer coat, the first layer is a thick dark gray outer coat that reaches the ground long and the inner undercoat gives them very good resistance to cold to temperatures down to minus 40 degrees. , to withstand the rigors of the Arctic.

Muskrats live in herds from 12-24 in winter and 8-20 in summer. During the summer, musk cows live in humid areas, such as deep valleys, and move up into higher mountainous regions in winter. Their food includes arctic willow grass, lichen and moss under the snow. Thyme is raised for meat, milk and feathers. Currently this species is protected, so the number is kept at a stable level.

Great Greenland shark

The Greenland giant sharks live in deep waters in the North Atlantic and Arctic regions, and these giant sharks not only survive in the cold water, but also have the longest lifespan of any species. are there any vertebrae on the planet – an average of 300 to 500 years old.

Greenland giant sharks have an extremely slow metabolic rate that helps control temperature and prolong life, and they are also the largest shark, can reach 6.4m in length and weigh about 1,000kg . Therefore, this shark is also very slow, often only hunting prey that has gone to sleep.

The price for a 500-year-old shark’s longevity is also not small. Specifically, it not only swim very slowly, difficult to find food, but the body also contains many parasites. Sometimes it even has to eat scavengers to relieve its hunger.

Besides, scientists are also hoping, the study of 500-year-old shark’s DNA could open a way to longevity for humans.

Before that, indigenous people in Greenland and Iceland used to believe in increasing longevity by eating Greenland shark meat.

Greenland shark meat is considered a specialty in Iceland, although toxic if not handled properly.

Snow Sheathbill

The snow Sheathbill is a brave, white, dove-like bird; This is the only native bird that lives on the surface of Antarctica and is the only species to breed here.

With their thick fur to help keep them warm, they live mostly on the ground, trying to pick up other birds’ scattered food scraps. They are also the only birds in Antarctica that do not have membranes.

So how can the snowy Sheathbill keep his toes warm while spending so much time on frozen ground? The secret lies in their life-long “bounce hobby”, they spend a lot of time hopping from leg to foot in order to reduce the coldness from the surface of the ice and snow. Furthermore, Snow Sheathbills also possess an extremely thick, fine coat that helps them retain heat well.

Weddell seals

If you are looking for a mammal that loves a few dozen degrees of negative cold every minute, then you will definitely love the Weddel seal.

They are the farthest Antarctic species of any kind, and spend most of their time living underneath the Antarctic ice, where they can hunt and avoid being caught by killer whales.

With the ability to dive deep to a depth of more than 600 meters, Weddell seals can stay underwater for up to 45 minutes and if they cannot break the ice to get the oxygen they need, they use their teeth to dig a hole. take the gas.

Antarctic seawater is actually warmer than surface air (which can drop to -70 degrees Celsius), so especially during intense winter storms, seals will stay warm by diving into the ocean. .

The arctic soil squirrel

If the current epidemic in the world makes you want to hibernate, you can consider the Arctic ground squirrel as an example.

Living in the arctic tundra in North America, where temperatures can drop below -63 degrees C in winter, they can escape the coldest winter by burrowing underground and sleeping for as long as eight. the month of the year.

When hibernation, the temperature in the brains of these squirrels can drop to just above freezing, while the body temperature can drop to -2.9 degrees C and the heart rate drops to just one beat per beat. minute. When the hibernation time is over, the squirrels need about three hours to warm up the body again.

This ability of arctic ground squirrels is due to them being able to cut off nerve connections and synapses to hibernate, then reconnect them immediately after awakening and warming the body, almost 2 – Every 3 weeks during winter.

In addition to its sublime cold tolerance, the arctic ground squirrel is also famous for its ability to fast for 8 months. The arctic ground squirrel body has the ability to recycle its own nutrients during hibernation for many months.
